Saw Chain Identification

To identify saw chain you need to know the following:

Gauge

Chain Gauge is the Drive Link's thickness where it fits into the guide bar groove, matching the guide bar gauge. The gauge of the chain and the gauge of the bar must match. Oregon has several gauges of saw chain: .043", .050", .058", and .063". Normal wear can make it difficult to accurately measure chain gauge on a worn chain. Always order by the number stamped on the drive link of your old chain to assure correct gauge. Please see table below for more information.

Pitch

Chain pitch is the size of the chain and is defined as the distance between any three consecutive rivets divided by two (measured in inches) Oregon chain is made in several pitches - 1/4" is the smallest, .325”, 3/8” Low Profile and 3/8" are the most popular, and 3/4” is the largest. Pitch is important because the drive sprocket must be the same pitch as the chain, and if applicable, the bar nose sprocket. The easiest way to determine the pitch of your chain is to look at the number stamped on the drive link. Please see table below for more information.

Cutter Type

There are various cutter types:
1. Chipper
2. Semi-Chisel
3. Chamfer-Chisel
4. Micro-Chisel
5. Chisel

Reduce Chainsaw-Related Injuries by Using Low Kickback Chain

Most of today’s chainsaws incorporate features that reduce kickback and other sources of chainsaw-related injuries. These built-in features include chain brakes, the front (left) hand guard, the bar tip guard, and low or reduced kickback chain and guide bars. In order to guarantee the effectiveness of these safety features, you need to make sure that your chainsaw is properly assembled and that all of the components are securely attached and functional. Unless you have experience or training for responding to chainsaw kickback, you should use low kickback chain. In North America, low kickback chain is packaged with a green label from the American National Standards Institute (ANSI).
